Severe headache triggered by cough, coitus, exertion
Sudden severe headache
Common Headache Types in TBI
Tension-Type Headache

Most common variety but least studied
–
–
–
–
Prevalence 30-78%
Episodic TTH – peripheral pain and central pain
mechanisms
Chronic TTH – central pain and peripheral pain
mechanisms
May overlap with milder migraines without aura
Tension-Type Headache






Intermittent OR continuous
Pressing or tightening
Lasts 30 minutes to
continuous
Bilateral location
Mild or moderate intensity
Not aggravated by routine
physical activity





Temporary relief with
analgesics
Increases throughout the
day
No nausea or vomiting
Either photophobia or
phonophobia, not both
Pericranial tenderness
Causes of TTH




Mental stress
Local myofascial release of irritants

Chronic TTH
Migraine

WHO ranks migraine
19th world-wide
among all disabilitycausing diseases
Diagnostic criteria


At least 5 attacks
At least 2 of the following:
– Unilateral location
– Pulsating quality
– Moderate or severe pain
intensity
– Aggravation by routine
physical activity


At least 1 of the following:
– Nausea and/or vomiting
– Photophobia and
phonophobia
HA lasts 4-72 hours
untreated
Characteristics



Commonly frontotemporal
Migraine without aura – more common, higher
attach frequency, more disabling
Migraine with aura – attacks of reversible focal
neurological symptoms that last for less than 60
minutes, followed by headache
–
Visual (zigzag, scotoma), sensory (pins and needles,
numbness), dysphasia
Pathophysiology of migraine

Migraine without aura
–

Nitric oxide (NO) and calcitonin-gene-related peptide
(CGRP) produce sensitization of perivascular nerve
terminals
Migraine with aura
–
–
Aura – regional cerebral blood flow decreases
Cortical spreading depression
Cervicogenic Headache

Possibly the appropriate
category for “whiplash”
associated headache
Diagnostic criteria





Pain referred from a source in the neck and perceived in the
head or face
Clinical, laboratory, or imaging evidence of disorder within
the C spine or soft tissues of the neck
Clinical signs that implicate a source of pain in the neck
Abolition of headache following diagnostic blockade of a
cervical structure or its nerve supply
Pain resolves within 3 months after successful treatment of
causative disorder or lesion
Occipital Neuralgia




Tingling and numb sensation in posterior scalp
area
Radiation in frontotemporal region
Localized tenderness to palpation
Restriction in cervical ROM
Chronic Headache



Tension-type headache
Chronic migraine
Hemicrania continua
Rebound headache

Can occur with regular use
of any analgesic or
abortive medication
including caffeine
Pharmacotherapy for Headaches


Abortive – stop or prevent the progression of a
headache or reverse a headache
Preventive (prophylactic) – reduce the frequently
and severity of the migraine attack, make acute
attacks more responsive to abortive therapy,
improve quality of life
Abortive Pharmacotherapy for Migraine
Headache
Moderate
Severe
Extremely Severe
NSAIDS
Naratriptan
DHE (IV)
Isometheptene
Rizatriptan
Opioids
Ergotamine
Sumatriptan (SC, NS)
Dopamine antagonists
Naratriptan
Zomitriptan
Rizatriptan
Almotriptan
Sumatriptan
Frovatriptan
Zolmitriptan
DHE (NS/IM)
Almotriptan
Ergotamine
Frovatriptan
Dopamine antagonists
Dopamine antagonists
Prophylactic Therapy for Migraine
First Line
High efficacy
Low efficacy
Second Line
High efficacy
Unproven efficacy
Beta-blockers
TCAs
Divalproex
Verapamil
NSAIDs
SSRIs
Methysergide
Flunarizine
MAOIs
Cyproheptadine
Gabapentin
Lamotrigine
Other possibilities




Riboflavin (Vitamin B-2) alters neuronal oxidative
metabolism
Magnesium reduces neuronal excitability
Treat associated disorders (depression, insomnia)
Monitor for dietary triggers
